1-8, in one embodiment, a scrubber brush assembly includes: the device comprises a shell 1, a rolling brush 2, a roller 3 and a side plate 4. A transmission mechanism for driving the rolling brush 2 to rotate is arranged in the shell 1, the rolling brush 2 is arranged at one end of the shell 1, and the roller 3 convenient for the rolling brush 2 to move is arranged at the other end of the shell. The side plate 4 is provided with a connecting piece 43, and the connecting piece 43 is used for limiting the position of the rolling brush 2 relative to the side plate 4 in the axial direction. One side of the roller brush 2 is connected with the connecting piece 43, and the other side is connected with a transmission mechanism in the shell 1. The side plate 4 is detachably fixed on the shell 1, the rolling brush 2 takes the symmetry axis of the shell 1 as a boundary, and the length of the rolling brush 2 close to one side of the side plate 4 is larger than that of the rolling brush 2 far away from one side of the side plate 4.

The rolling brush device of the floor cleaning machine in the embodiment is adopted and is hereinafter referred to as the rolling brush device. Can dismantle curb plate 4 through the setting, be convenient for dismantle the washing to the inside round brush 2 of round brush device. The round brush 2 adopts asymmetric setting to the symmetry axis of casing 1 is the decomposition line, and the round brush 2 length that is close to 4 one sides of curb plate is greater than 2 length of opposite side round brush, increases the area that round brush 2 washd ground, improves the cleaning efficiency of round brush 2, and is especially unilateral when leaning on the wall and washing the ground. Through the connecting piece 43 who is connected with the round brush 2, the position of the relative curb plate 4 of round brush 2 axial that can be better fixed can prevent round trip movement of round brush 2 in the axial, can guarantee the cleaning performance of round brush 2 again.

The coupling member 43 includes a base plate 431 and a coupling end, and the roll brush 2 is coupled to the coupling end and abuts against the base plate 431. As shown in fig. 8, there is a gap L between the roller brush and the outer side wall of the side plate, the gap L including the thickness B of the side plate and the distance C between the roller brush and the inner side wall of the side plate.

As shown in fig. 3, the left side of the roller brush 2 is connected to the side plate 4, and the right side is connected to the transmission mechanism inside the housing 1, and a space is required between the transmission mechanism and the right side of the housing 1 to install a required driving member, such as a motor. The side plate 4 is a plate-shaped structure, the bottom plate 431 is arranged on one side of the connecting piece 43 close to the side plate 4, the roller brush 2 is contacted with the bottom plate 431 to limit the axial position of the roller brush 2, and a gap as small as possible, such as 0.1mm, is arranged between the side plate 4 and the bottom plate 431.

This kind of structural design can prolong the length that rolling brush 2 is close to 4 one sides of curb plate as far as, improves the washing area of rolling brush 2. Better, can shorten the distance that round brush 2 and wall can contact to within 3-8mm, realize better unilateral wall-attaching and clean the effect. Wherein the thickness B of the side plate 4 is not less than 3mm to ensure the structural strength of the side plate 4. All directional terms, such as front, back, left and right, are used for better describing the scheme of the application and should not be construed as limiting the application.

The connecting piece 43 can be arranged rotatably relative to the side plate 4, and the connecting piece 43 and the roller brush 2 can rotate synchronously. The connecting piece 43 is detachably connected with the rolling brush 2 in a concave-convex matching way. Unsmooth cooperation can carry out spacing preventing the drunkenness to the axial of round brush 2 on the one hand, and fixed round brush 2 that also can be better guarantees the stability of round brush 2 during operation. The detachable connection is more convenient when the rolling brush 2 is maintained and cleaned.

Specifically, the housing 1 is provided with an installation groove 11, the side plate 4 on the same side as the connecting piece 43 is fixedly provided with the installation ring 41, and the side plate 4 detachably connects the installation groove 11 and the installation ring 41 through a locking piece.

The locking piece comprises a knob 5 and a lock catch 6, and the knob 5 is detachably connected with the lock catch 6. At least one first limiting block 12 is arranged on the side wall of the mounting groove 11, a limiting groove is arranged on the first limiting block 12, and at least one third limiting block 63 is arranged on one side, far away from the knob 5, of the lock catch 6. The lock catch 6 can rotate along with the knob 5, and the third limiting block 63 can rotate along with the lock catch 6 and is embedded into the limiting groove of the first limiting block 12.

As shown in fig. 2 and 6, the first stopper 12 and the third stopper 63 have a hook-like structure or a bent portion. When the third limiting block 63 rotates to the first limiting block 12 through the knob 5, the third limiting block cannot rotate continuously, and locking is achieved. When the knob 5 is rotated in the reverse direction, the first stopper 12 and the third stopper 63 are unlocked. Preferably, as shown in fig. 5, a handle fastening position 51 may be provided on the knob 5 near the outer side, so that the user can rotate the knob 5 quickly. Better, detain hand position 51 and be the groove structure who sets up on the knob 5, detain hand position 51 and sunken to being close to 6 one sides of hasp, guarantee that the curb plate 4 outside is comparatively level and smooth, and then when round brush 2 is close to the wall during operation, can shorten the distance between round brush 2 and the wall.

The inner side wall of the mounting ring 41 is provided with a rib ring 42, one side of the rib ring 42 is provided with a lock catch 6, and the other side is provided with a knob 5. The rib ring 42 is provided to prevent the knob 5 and the lock catch 6 from moving back and forth relative to the axis of the mounting ring 41.

The latch 6 is provided with a latch part 62, and the latch part 62 is fixed on the knob 5 in a latch manner. The buckling part 62 is convenient for detachably connecting the lock catch 6 with the knob 5, and further, the lock catch 6 and the knob 5 can be connected firmly through screws, so that the knob 5 and the lock catch 6 can rotate synchronously.

The side plate 4 on the same side as the connecting piece 43 is provided with the guide block 44, the side surface of the shell 1 is provided with the guide groove 13, and the guide block 44 is matched with the guide groove 13 in a concave-convex mode, so that the side plate 4 can be conveniently and quickly installed on the shell 1.
